It is characterized in that: multiple rows of the stress-bearing members are provided, and each row is arranged from top to bottom. Transverse and diagonal support beams are installed on the stress-bearing members. There are two relatively arranged transverse support beams installed on the first row of stress-bearing members, and multiple diagonal support beams are installed between the transverse support beam below and the remaining stress-bearing members. A triangular support frame is formed between the diagonal support beam, the transverse support beam and the stress-bearing member, and equipment is erected on the transverse support beam.

[0005] Preferably: Multiple diagonal support beams are provided, and the length of each diagonal support beam is different. The angles between the diagonal support beams and the transverse support beam are all α, and α is between 30° and 60°.

[0006] Preferably: Two short beams are also welded on the transverse support beam. A square placement hole is formed between the two short beams and the transverse support beam, and screw holes are provided on the transverse support beam for fixing the equipment.

[0007] Preferably: The short beams, the transverse support beams and the diagonal support beams are all stainless steel hollow tubes, and heat insulation materials are filled in the cavities of the hollow tubes to avoid the aggregation of air and moisture and increase the overall heat insulation effect of the support structure.

[0014] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "transverse", "vertical", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the device or component referred to must have a specific orientation, so it cannot be understood as a limitation to the present utility model.

[0015] The following will introduce the present utility model in detail with reference to the drawings: As Figure 1-2As shown in the figure, a lateral support bracket structure for small equipment inside a cold box includes a cold box body. On one side wall of the cold box body, a force-bearing member 1 is installed. The force-bearing member 1 is arranged in multiple rows, with each row arranged from top to bottom. On the force-bearing member 1, support crossbeams are installed horizontally and obliquely. There are two horizontally arranged support crossbeams 2 arranged opposite to each other and installed on the first row of the force-bearing member 1. Below it, between the horizontally arranged support crossbeam 2 and the remaining force-bearing members, multiple obliquely arranged support crossbeams 3 are installed. The obliquely arranged support crossbeam 3, the horizontally arranged support crossbeam 2, and the force-bearing member form a triangular support frame 4. An equipment is installed on the horizontally arranged support crossbeam 2. The horizontally arranged support crossbeam is connected to the equipment through connecting bolts, and the material of the connecting bolts is A2-70 stainless steel.

[0016] There are multiple obliquely arranged support crossbeams 3, and the length of each is inconsistent. The angle between it and the horizontally arranged support crossbeam 2 is the same, which is 35°. Two short beams 5 are also welded on the horizontally arranged support crossbeam 2. A square placement hole 6 is formed between the two short beams 5 and the horizontally arranged support crossbeam 2. And screw holes 7 are opened on the horizontally arranged support crossbeam 2 for fixing the equipment.

[0017] The space formed by the angle between the horizontally arranged support crossbeam and the obliquely arranged support crossbeam in the present utility model is used to ensure sufficient space for the fixing bolts of the equipment lugs installed at the screw holes, thereby ensuring the actual installation effect.

[0018] The short beams 5, the horizontally arranged support crossbeam 2, and the obliquely arranged support crossbeam 3 are all stainless steel hollow tubes. Heat insulation materials 8 are filled in the cavities of the hollow tubes to avoid the accumulation of air and moisture and increase the overall heat insulation effect of this support structure. At least one end of each hollow tube is sealed with a steel plate. At one end of the horizontally arranged support crossbeam 2 and the obliquely arranged support crossbeam 3 located on the force-bearing member 1, a reinforcing plate 9 is welded to increase the overall strength. In the present utility model, the support crossbeam and the short beam are fixed by welding, thereby ensuring the overall strength and beautiful flatness.

[0019] The lengths and positions of the horizontally and obliquely arranged support crossbeams of the present utility model are determined according to the actual on-site situation and the specific positions of the force-bearing members of the main structure of the cold box, so as to meet the actual requirements.

[0020] The lateral support bracket structure for small equipment inside the cold box designed by the present utility model, after improvement, has less steel consumption in the overall support structure, reducing the one-time investment cost; this support structure occupies limited space, and the limited space inside the cold box can be left for other equipment and pipelines. Just because it occupies limited space, it can be flexibly installed in each limited space inside the cold box, making full use of the precious space resources inside the cold box, and even reducing the external dimensions of the entire air separation cold box; the connection method between the components of this support structure is simple, avoiding the complex node design cost, and can be classified by small equipment of different sizes and weights, designed as standardized drawings, and directly selected according to the equipment weight and size grades, avoiding the repeated design work of different equipment for each project. The material selection is streamlined, easy to process, and has low manufacturing cost, which is beneficial to improving the overall production efficiency. The construction operation of the present utility model is simple and the positioning is accurate, providing firm and reliable technical support for large cryogenic equipment.

[0021] For the installation of the support bracket structure of the present utility model, appropriate welding electrodes and welding processes should be selected, and welded by certified welders to ensure the welding quality; all welds should be inspected for appearance and no welding defects should exist; it should meet the requirements of relevant national standards.
